FRIEND SMITH, OF ,BRIDGEPORT, CONNECTICUT, ASSIGNOR TO THE NATIONAL LOCKWASHER COMPANY, OF NEWARK, NEW JERSEY, A CORPORATION OF NEW JERSEY.

COMBINED SASH HOLDER AND WINDOW RELEASE.

Application filed August 18, 1925. Serial No. 50,993.

This invention relates to sash holders, but

' more particularly has reference to devices of this description such asare commonly used on railroad car windows and are equipped with avertically guided plunger pin, which, when the sash holder lever israised to release the window from side racks in the casing, is drivendownwardly againstthe sill of the window with suflicient force torelease the latter if it be stuck;

Constructions ofthis sort are not new as is evidenced by Letters PatentNo. 1,547,775, issued July 28, 1925, to John L. Armstrong, but theobject of the present invention is to positively connect the plunger pinwith an eccentric element that is carried by the'sash holder lever, sothat the upward and clownward movements of the latter will cause saidpin to be projected and retracted.

In the accompanying drawing Figure 1 is an inside elevation showing theusual sash holder equipped with this invention, with the parts in theirnormal position.

Figure 2 is a similar view but showing the sash holder lever operated towithdraw the side (atch of the sash, and the impinging bolt thrustdownwardly.

Figure 3 is an inside view of the casing with the parts removed, and

Figure 4 is a detail perspective of the sash holder lever.

, Similar numerals of reference will be used to denote like parts in theseveral figarcs of the drawing. 7

1 is the casing of thesas h holder having formed therewith the usualdowels 2 to eX- scribed, since this is the ordinary sash holder commonlyused on railroad car windows.

Integral with the inner portion of the member 3 and extending laterallytherefrom is a hollow hub 7 which surrounds the post t in pivotalrelationthereto, the inside surcoil spring interposed between 7 face ofsaid hub being concentric with the axis of the pivot of said member3,while the outside periphery of said hub is eccentric to said axis and isdenoted by'the numeral 8.

Slidably housed within the bottom of the casing and within a boss 9projecting therefrom is a plunger pin 10, which latter is capahle offree movement beyond said boss to contact the window sill which isdenoted by the numeral 11. g

The upper portion of this pin is enlarged and has therein a circularopening 12 through which'the eccentric 8 extends snugly'but is free torevolve within this opening.

I Vhen the parts are in normal position with the sash closed, as shownat Figure 1, the uplift of the lever 3 will disengage the part 6 fromthe usual side rack in the casing, and the continued uplift of thislever will cause the eccentric 8 to force the pin 10 downwardly againstthe sill 11 so as to release the lower rail of the sash it stuck to thesill, as is illustrated at Figure 2, and when the sash has been raisedsufliciently and the lever released, the spring!) will cause the innerend 6 to engage the side rack in the easingto hold the sash open, andthis swinging movement of the lever around'the post t will cause-theeccentric 8 to operate to retract the pin to normal position, so that,when the sash is open, there will be no projection of the pin below thesash.

What is claimed is A combined sash holder and window release, comprisinga casing, a sash holder lever pivoted at its inner end within saidcasing and having a hub extending laterally from said end and forming apart of the pivotal portion, said hub having an eccentric eri 31161 anda verticall disposed alun er pin guided within the bottom of said casingand having in its-upper enda circular opening which closely its aroundsaid periphery, whereby the upward movement of said'lever will. causesaid pin to be forced downward against the window sill and the upwardmovement will return said pin to .its normal elevated position.

In testimony whereof I afhx my signature hereto.

FRIEND W; SMITH.
